GEORG HOLZAPFEL, OF ESSEN-ON-THE-RUHR, GERMANY.

APPARATUS FOR COMPRESSING GASES AND VAPORS.

- To all whom it may concern:

Be it known that I, GEORG HOLZAPFEL, a subject of the King of Prussia, residing at 5 Kanonenstrasse, Essen-on-the-Ruhr, Germany, have invented new and useful Im provements in Apparatus for Compressing Gases and Vapors, of which the following is a specification.

It is known to compress gases and vapors by subjecting them to the action of a liquid which moves with such velocity that it is capable by virtue of its energy of fiow to carry away the medium to be compressed to a point at a higher pressure. In this method the liquid was brought into the compression chamber in the form of thin jet disks. This was attained by arranging upon the periphery of a turbine wheel of a rotating jet pump an annular nozzle with a narrow outlet slit and by hurling the liquid through this jet or nozzle into the compressing chamber. Now it is not always possible, to arrange this annular nozzle on the periphery of a turbine wheel. Thus for example it may happen that in the case of small delivery of the pump, the outlet area of the slit becomes insuflicient because one is dependent as regards the diameter of the nozzle upon the diameter of the turbine wheel. The latter is dependent in its turn upon the number of revolutions and the volume delivered by the pump. It is easy to see therefore that it is impossible in the case of the known arrangement to build pumps of small capacity with a low number of revolutions. The latter condition has however always to be fulfilled in the case of belt driving. Furthermore, itis imaginable that where the use of a comparatively large number of turbine pumps of small capacity is necessary, the driving of each separate small pump will not be economical.

By means of the improved apparatus hereafter described, these disadvantages are obviated. This end is attained by separating the liquid pumps and jet ejectors by a space.

The present invention comprises apparatus such as is described in the specification of my co -pending application, Serial No. 599,9st8, filed December 29, 1910, but in which the liquid for compressing the air or gas, instead of being drawn into and forced through the annular nozzle by the rotation of the turbine wheel forming part of or placed within the walls of the nozzle, is admitted to the said nozzle under pressure,

so that the rate of flow of liquid through the nozzle is not dependent upon the rotation of any part of the apparatus, but upon the pressure at which the fluid is admitted to the nozzle.

Figure l is a central sectional view of a compressing apparatus embodying my invention, Figs. 2 and 3 are similar views showing other embodiments of my invention.

A constructional form of the apparatus which constitutes the subject matter of this invention is shown in Fig. 1 in the accompanying drawing.

In a casing which in general resembles that of a turbine pump, is mounted a shaft on which carries a suitably shaped revolving body I) which is mounted either fast or movable on the said shaft. The faces 6 I2 form the inner walls of annular nozzles, the outer walls b b of which are arranged in the manner shown in the drawing.

The nozzle wall 72 can be moved along longitudinally by means of the hand wheel 0, so that the left hand nozzle slit can be adjusted from the outside. In this apparatus the capacities of both nozzles can be simultaneously regulated from outside. If for example the left hand nozzle slit be contracted by turning the hand wheel 0, the fluid pressure in it will rise, while it does not rise on the right. The body I) will therefore move such a distance to the right, until the pressures are once more equal and the nozzle slits of equal width. If the body I) be also allowed to rotate freely on the shaft a, any deposition of dirt and foreign bodies in the nozzle slit will be prevented as will easily be seen. The revolving body may be keyed on the shaft and the shaft set in rotation through the medium of a worm mounted thereon by the pressure of the liquid to be subdivided.

The way, in which the liquid is introduced into the apparatus described is of no consequence to the essential feature of the invention. It may be taken from a pipe delivering water under pressure or be supplied by a pump or the like.

The present invention therefore enables thin jet disks of liquids to be used in such cases as are described in the introduction to this specification. Since the arrangement described does not contain a turbine wheel, one is not boundto maintain fixed dimensions. Separate driving of each individual apparatus is likewise by no means necessary; on the contrary any desired number thereof may be supplied from a central source.

While in the constructional example as before described the movable body the faces of which form the inner Walls of the annular nozzles is arranged longitudinally movable on the shaft a and one outer nozzle Wall can be adjusted from the outside, this is not absolutely necessary, but may be varied in the manner hereinafter described and illustrated in F 2 and 3 of the annexed. drawings Which constitute a second constructional example of the invention.

In Fig. 2, the shaft a is mounted to revolve in a. central bearing forming part of the casing (Z. At each end, this shaft carries a revolving body I), each provided With. an annular member C or the thin edges of Which form the outer Walls or lips of the annular nozzles, the inner Walls C or G of which are secured on the casing (Z. By means of nuts at the ends of the shaft (4 the position of the revolving bodies may be shifted and the Width of the nozzle orifices may be adjusted. This adjustment can be made from the outside, and for this purpose openings (Z are provided. In this case the liquid enters at E and leaves the casing at F.

The modification illustrated in Fig. 3 is very similar to the previous one. The shaft; 6 is in this case also mounted in the central portion of the casing d and the nozzle walls 5 are carried by the revolving bodies I) keyed on the shaft 6 Nuts are also pro-J vided in this case at the ends of the shaft for the adjustment of the position of the revolving bodies 6, but this adjustment cannot be made from the outside. In order to tighten or loosen these nuts, the caps d have therefore first to be removed. The nozzles b are secured on fixed parts I) of the easing (Z Claims:
